Green Tea and Perfect Skin
Green Tea Improves Skin Protection and Structure
Journal of Nutrition & reported on the Ingredients Network: consumption of green tea polyphenols improved skin protection and skin structure in women.
German academic researchers assigned 60 women to consume a one-liter beverage with green tea polyphenols (1402 mg of total catechins) or a control beverage daily for 12 weeks.
Skin photoprotection, structure, and function were measured at baseline, week 6, and week 12.
“At week 12, subjects consuming the green tea beverage showed increased blood flow and oxygen delivery to the skin along with improvements in structural skin characteristics.“
Skin hydration in the green tea group improved by 17% compared to a 5.2% increase in the control group (likely attributed to increased fluid intake with the one-liter beverage). Skin elasticity, toughness, scaling, density, and water homeostasis were also positively affected by the intervention.
At weeks 6 and 12, UV-induced skin redness was decreased by 16 and 25% with green tea consumption, compared to placebo.
“The study showed that dietary constituents protect skin and improved overall skin quality. Regular consumption of a beverage rich in tea flavanols contributed photoprotection against harmful UV radiation and helped maintain skin structure and function.”
